The 74HCT157PW from NXP Semiconductors is a high-speed Si-gate CMOS device that falls under the category of multiplexers. This particular component is designed to operate with a power supply range of 4.5 V to 5.5 V, making it compatible with TTL (Transistor-Transistor Logic) levels. The device is characterized by its low power consumption and high noise immunity, typical of CMOS integrated circuits, combined with the ability to drive 10 LSTTL (Low-power Schottky TTL) loads.

The 74HCT157PW is a quad 2-input multiplexer that allows digital information from two different sources to be selected and fed into a single output line. Each multiplexer has two select inputs (S0 and S1), four data inputs (1A0 to 1A3, 2A0 to 2A3), and one output (1Y to 4Y). The select inputs determine which set of data inputs (1A0 to 1A3 or 2A0 to 2A3) is connected to the corresponding output.

This device comes in a TSSOP-16 (Thin Shrink Small Outline Package) with a body width of 4.4 mm. The 74HCT157PW is suitable for a variety of applications including data routing, signal gating, data selection, and many other functions that require the option to choose between multiple inputs.

Key Features:

• Compatible with TTL input levels
• Wide operating voltage range: 4.5 V to 5.5 V
• Low power dissipation: 8 µA max ICC
• High noise immunity: 1 VCC (typical)
• Low propagation delay: 13 ns (typical)
